To all 'whom z'tfmay concern! i l Be it known that I, JOHN E.-SEDLAGEK,

a citizen of -the United StateSyresiding at Howells, in the county of Colfax and State of Nebraska, have invented certain newand useful4 Improvements in Draft-Equalizers, of which-the following is a specification,

referencebeinghad to the accompanying drawings. Y y

This invention relates to certainimprovements in draft equalizers andfhas 'rela-tion.

more particularly to a. device ofjtliis general character especially designed and adapt# ,v

ed for use in connectionwithbinders` or the like, and it is an object of thei'nvention to provide a device of this Vgeneral character having novel and improved meanswhereby a direct pull is imposed upon lthe vehicle.

It is also an object of the invention toprovide a novel and improved device of this general character whereby the'animals are relievedA from the ma]or .portion ofv the weightof the draft equalizer.

The invention also has for an object to provide a novel and improved device of this general character wherein an equalizing ele- -pole of the vehicle' and wherein the trees are directly engaged with the opposite lend,

portions of the draft element. Y

The invention consist-s in the details of' proved draft equalizer wherein certain im` portant advantages are attained and the de-V vice rendered simpler, less expensive and otherwise more convenient and advantageous for use, as will be hereinafter more fully set fort The novelfeatures of my` invention will hereinafter be definitely claimed.

In order that my invention may be the better understood I will now proceed to describe the same with reference to the accompanying drawings wherein:v

Figure 1 is a view in top plan of a draft equalizer constructed inl accordance with an embodiment of my invention, the co-acting truck pole being shown in fragment; and

Fig. 2 is a fragmentary view partly in rear elevation and partly in section ofthe equalizer as herein embodied, certain o f the parts being omitted for. clarity in disclosure.-

As disclosed in the accompanying drawings P denotes the truck pole as generally- 'wardly of the outer end thereof.'V Y

The shorter arm 7 is disposed in a tion substantially rearwardly Vofthe truck pole P and operatively engagedA with theV member 12 extends a predetermined distance `of. Said flexible member 9 is-also opera-k l tively engaged with the'guide pulley' 3. The

i'io n in advance of the beam or extension 2 and is secured to the elongated tree 14 at substantially the longitudinal center thereof.

Pivotally engaged with the opposite end v portions of the tree 14 are the trees 15. The.

pivotal mounting 16 of each of the trees 15 is such as to afford an outwardly disposed short arm a and an inwardly directed long arm Z). To the outer end portion of each of the smaller arms a is operatively engaged a swingle tree 17. The. inner or adjacent ends of the longer arms Z) of the trees 15 are connected by a clevis 17 or the like and secured to said clevis is a swingle tree 18.

To one skilled in the art it will be self evident that a draft equalizer constructed in accordance with an embodiment of my invention assures a direct pull of the draft animals and also permits the draft animals to be so hitched to a binder or the like as to prevent the animals from traveling through the standing grain and which is of particular import. It will also be noted that the beam or extension 2 is capable of swinging or pivotal movement relative to the truck pole P. This in practice has materially increased the efliciency of the equalizer.

From the foregoing description, it is thought tobe obvious that a draft equalizer constructed in accordance with my invention is particularly well adapted for use by reason of the convenience and facility with which'it may be assembled and operated and it will also be obvious that my invention is susceptible of some change and modification without materially departing from the prin- Copies of thispatent may be obtained for ciple and spirit thereof, and for this reason I do not wish to be understood as limiting myself to the precise arrangement and formation of the several parts herein shown in carrying out my invention in practice except as hereinafter claimed.

I claim:

In combination with a draft pole of a vehicle, a beam having an end portion overlying' the pole and extendingkr laterally therefrom, a truck, an upstanding member carried by the truck and disposed through the draft pole and the beam for pivotal con-k nection with said pole and beam, said upstanding members being provided with an annular flange uponwhich the pole rests, a member comprising a pair of angularly related arms pivotally engaged with the pole at a point inwardly of the beam, a pulley rotatably supported by the upstanding member of the truck at a point above the beam, a guide member carried by the outer end portion of the beam, flexible members secured to the free ends of the arms of the first named member, one of said members coacting with the pulley and the second of said iieXible members with the guide member carried by the beam, and trees to which the forward end portions of the flexible members are connected.

In testimony whereof I hereunto aflix my signature in the presence of two witnesses.
